Description

Electroneurography refers to the technique used to test and quantify the nerve conduction and impulse propagation along motor and sensory nerves. A synonym is nerve conduction study. In principle, a peripheral nerve is stimulated by a short electrical pulse usually applied transcutaneously. The responses are recorded using electrodes applied over the muscle innervated by the nerve (motor nerve conduction), from the skin (sensory nerve conduction) or from another part of the nerve (mixed nerve conduction). The time the impulse takes to travel from the stimulation to the muscle is called distal motor latency and is measured in milliseconds. The amplitude is a measure of the number of nerve or muscle fibers activated. The stimulation has to be strong enough to activate all nerve or muscle fibers. By stimulating the nerve at two different sites along the nerve, the motor conduction velocity can be calculated by diving the distance by the...
